This paper presents an annotation scheme for marking subjective content in meetings, specifically the opinions and sentiments that participants express as part of their discussion. The scheme adapts concepts from the Multi-perspective Question Answering (MPQA) Annotation Scheme (Wiebe et al., 2005; Wilson, 2008), an annotation scheme for marking opinions and attributions in the news. The adaptations reflect the differences in multiparty conversation as compared to text, as well as the overall goals of our project.
